Rugrats: Mysteries [2003]

Murmur on the Ornery Express:
The whole gang's along on an overnight train ride through Little Biendeltown, a re-creation of a town from "the old country." But the ride quickly takes a mysterious turn when Chas reads about a train robber on the loose and Chuckie's Wawa and Minka's necklace disappear!
Thank goodness Chuckie can count on Tommy to get Wawa back "if it's the lastest thing I never do."

Two Bonus Episodes:

The Fun Way Day:
The first day of business at chas and Kira's new coffee café isn't doing well, so Kira recommends hiring a Feng Shui expert to "create a natural environment in tune with the Earth's natural energy." But the Rugrats think the "fun way" guy came to play a great new game with them!

At the park, Angelica wants to play with a couple of 4-year-old girls who want nothing to do with 3 year olds like her. So when she overhears them wishing they had a real baby to play with, Angelica has an idea and promises to be nice to the babies forever if she can give the older girls Phil to play with.
